WASHING-MACHINE.

Specification of Letters Patent.

Application filed February 11 1908. Serial to. 415,456.

chines, having for its object the production I of a simple and effective machine for subjecting the clothes to a boiling operation while in motion, the machine embodying means for atfording a thorough and complete circulation of hot water and steanl through the clothes and the distribution or spraying of such hot water and steam throughout all the clothes contained in the machine.

lVith the above and other objects 'in' view, the nature of which will more fully appear as the description proceeds, the invention 'consists in the novel construction, combination and arrangement of parts hereinafter fully described illustrated and claimed.

In the accompanying drawings :Fignre 1 is a perspective view of a complete washing machine constructed in accordance with the present invention, showing the cylindrical body in position to admit of the insertion or removal of the clothes. vertical diametrical section through the clothes receptacle after said receptacle has been inverted or placed in its operative position. Fig. 3 is a vertical longitudinal section through the machine illustrating the circulation. Fig. liS a detail perspective view of the hot water and steam chamber.

The machine contemplated in this inVe'n-'- tion comprises a main body 1 of suitable dimensions and preferably rectangular in shape, the interior of said body being divided by a vertical partition 2at a suitable point into a boiler 3 and a dead air or insu-- At tire top, the body 1 is.

lating chamber 4. prr'ivided with an outwardly projecting flange or ledge 5. The dead air chamber 4 is closed by a top wall 6 while the remainder of the body above the water chamber or boiler 3 is left open with theexception of a narrow lid section 7 which is hinged at 8 adapting the same to be lifted and thrown backfor a purpose which will appear.

in. the open top of the boiler or'waterv Fig. 2 is a chamber ,3 is arranged a cylindrical clothes receptacle 9, the same being mounted loosely on a shaft 10 l v which said receptacle is supported. The shaft 10 projects outside of the heads on the cylinder, as shown in Fig. 2, preferably passing through-centrally arranged stufling boxes 11 on the cylinder heads, the projecting portions of the shaft extending over the top ed es of the opposite sides of the body, as indicated in Fig. 1. These projecting portions of the shaft are journaled in bearings 12 mounted to slide 'on the flanges 5 and being held in place by bolts 13, which work in slots 14 in said flanges, thereby enabling the cylindrical receptaclef to be moved to a limited extent lengthwise of the body 1, the object of which will-be explained later.

Extending around the outer surface of the receptacle 9 and concentric thereto is a spray nozzle or conduit 15, made tapering as indicated by dotted lines inFig. 2, one end of which is relatively small or narrow and provided with an opening 16 adapted to receive a nipple 17 extending inward from the partition 2., said nipple containing one end of an arcuate circulating connection or pipe 18 which is connected with the dead air chamher t, the opposite end of said pipe 18- being inserted and held in another opening'19'in the partition 2 at apoint lower down than the nipple 17, the latter being located at and near the top of said partition 2. From the .point where the opening 16 is formed the nozzle or conduit 15 gradually increases in width and at its opposite end where it is expanded to the greatest extent, spray ports 20 in the form of perforations are provided in the outer wall of the receptacle 9 whereby the hot water and steam passing through the nozzle 15 is distributed and sprayed downward directly upon the clothes in the receptacle 9, the spray portsbeing arranged at-the top of said receptacle.

Opposite the spray ports 20, the cylindrical receptacle 9 is provided witha perforated door 21 which is hinged at one side as at 22 and provided at the opposite side with a slot 2-3 adapted to pass over an eye or staple 24 through which a locking pin 25 may be inserted to hold said door closed. In addition to its function as a door, the-part 21 acts as a drip plate or discharge for the water through the bottom of the cylinder when the same is reversed from the position shown in Fig. 1 to the position shown in Fig. 3, the latter being the opposite position.

In the bottom 01 the compartment 3 there is arranged a'hood 26 which in connection with the bottom of the body 1 forms a hot water and steam chamber 27 which gradually slopes from one end to the other. This hood is provided at'its shallow end with a plurality of drain holes 28 while at the opposite or larger ends said chamber is provided with a projecting nipple 29 which. is received in the adjacent lower end or the circulating connection or pipe 18 as clearly shown in Fig. 3.

30 designates a drain cock for drawing oli' the water of the machine.

. The shaft 12 is provided within the clothes receptacle 9 with a dasher or stirrer which may consist of one or more arms 31 projecting rearwardly from the shaft and, if desired, formed integrally therewith as shown in Fig. 2. The shaft is also provided at one end with an operating crank or handle 32,

whereby said shaft may be turned for the purpose of rotating the dasher or stirrer within the cylindrical clothes receptacle, the

latter being held stationary.

To place the clothes in the receptacle 9, the hinged lid 7 is swung upward and the receptacle 9is moved toward said lid until said receptacle is disconnected from the circulating pipe 18. The receptacle 9 is then turned until the door 21 is at the top. After placing the clothes in the cylinder, the door is closed and fastened in the manner described. The cylinder is then turned through halt the revolution or reversed so as to carry the door 21 which constitutes a drip plate to the bottom. This brings the opening 16 into alinement with the nipple l7 and the receptacle 9 is then slid toward the nipple until an engage mentis eilected after which the lid 7 is swung downward to its closed. position where it acts as a back stop for the receptacle 9. In this position the spray ports 20 are disposed at the top of the receptacle. The machine as a whole is placed over the fire and the necessary amount of water introduced into the chamber 3. This water finds its way into the hot water or steam chamber 27 and when sufiiciently heated to produce. steam, such steam combined with hot water is forced through the circulating connection 18 into the concentric spray nozzle 15 and then through the spray ports 20 upon the clothes, the latter being kept in motion by the dasher or stirrer 31. After passing through the clothes, the water finds its way out through the drip plate or'door 21 and in a comparatively cool condition falls into the compartment 23, passing from there into the chamber 27 where it is again brought to the boiling point. In this way a complete circulation of steam and hot water is maintained in' the machine. I claim l. A 'ashing machine comprising a boiler, V

a reversible clothes receptacle mounted therein, a shalt on which said. receptacle is supported, mounted in slide hearings on the boiler, a circulating connection communicating with the boiler and having a detachable engagement with said clothes receptacle, a dasher or stirrer on said shaft, working within the clothes receptacle, and a movable stop for holding said clothes receptacle in engagement with the circulating connection.

2. A washing machine comprising a boiler, a cylindrical clothes receptacle reversibly mounted therein, a perforated plate having a jointed connection with one side of said receptacle, a spray nozzle communicating with the opposite side of said receptacle and mounted thereon, a dasher or stirrer working in said receptacle, and a tapering circulating connection communicatingwith the boiler at 'one end and communicating with said nozzle at the other end.

In testimony whereof l alhx my signature in presence of two witnesses.
